Image via Before You Start The obvious first step here is to. But before you do anything else, a word of caution: once you've used the OS X installer, it will automatically delete the file you need to make the backup disk, so you'll want to either make a copy of the installer or create your disk before you upgrade. You can use a USB flash drive, external hard drive, or DVD-R disc, but the USB drive is quicker. If you're using a USB drive, it has to be formatted as 'Mac OS Extended (Journaled)' and set to partition type 'GUID Partition Table' in order to work. Image via Once inside, browse to the ' Contents > SharedSupport' folder where there will be a file called ' InstallESD.dmg.' This is the image file that contains the information you need to create the backup disk. Getting Lion from the App Store is convenient, but if you want a physical copy of the installation, you can easily make your own Lion install DVD or USB drive with Disk Utility. Step 2: Open Disk Utility (located in your Applications > Utilities folder). Step 3: Drag and drop the ' InstallESD.dmg' into the list of drives on the left and select it. This should make it appear in the Source box on the right. If not, you may have to click the ' Restore' tab as seen below. Have an old Mid-2007 MacBook, hard drive died, but I had another hard drive from an old Windows laptop. Plugged it in and to my honest surprise the laptop successfully booted into Windows 8.1 without any issue. Sadly I was unable to find any compatible drivers for the trackpad for Windows 8, not surprised really. Anyway, long story short~ I wanna stick OS X back on this laptop, however I am having trouble getting the installer to boot from my USB drive. I downloaded a copy of OS X Lion and mounted it as many guides told me too, but on trying to boot from the USB on my MacBook it seems to fail and just resort to booting into Windows instead. Any tips, as every guide online is just telling me to do what I have already done ten times already (Restoring from image in transmac) Here is a video too, just to confirm the USB boot option is showing, just seems to be going nowhere? Have tried several other disk images of Lion and Snow Leopard with no joy - although the Snow Leopard one actually showed a white screen with an X in the centre before trying to boot windows. Any ideas at all? Completely formatted hard drive to HFS, no change. Downloading some new image files in case maybe i just got an iffy copy, but i am not too hopeful. I need my laptop this weekend so i am going to just (try to) stick ubuntu on it for now. Update: haha so the macbook 2.1 efi firmware is apparently trash and ubuntu usb is not booting~ put hard drive in my pc, installed ubuntu on it, put it back in laptop, white screen with flashing? Folder downloading snow leopard again to try and see if that can boot from usb. Failing this i guess i'll just have to go without my laptop this weekend and borrow a friends. Oh, don't think I mentioned it, my MacBook has no cd-rom drive as it died many moons ago. What files does calendar for mac use for importing google calendar.
